Flowcode Support Board

Another suggestion is to open a terminal program on the USB com port used by the esp32 - I use putty and realterm but many others are available. Use 115200 baud and you should get some info on run - sometimes something useful like pin... can't be used for...
You'll need to close it again before you reprogram the esp (an advantage with realterm is you can just click to do this)

Hi

I can't find it just now, but I had a link to a chart that documented what pins you cannot use with an ESP. Could you try using two alternative pins for the data?

Regards

Thanks for the replies I have downloaded realterm and will have a play after work, I also found this link

after reading chipfryer27's post. It looks like some of pins I have assigned might be input only. Hopefully will be able to fix after work
